Fullerton has not been colder than 68 for the high since February 20. That could change this weekend.
SSTs are well above average, but this could knock them down, especially if weak troughing continues next week.
Kind of hard to feel much optimism for next winter around here though if the Nino gets to be very strong. If it's more borderline moderate/strong, then there is some precedent (though limited) for a decent winter locally. But very strong Nino, forget about it. All about hoping to luck into a good storm or two in the midst of what would feel more like extended Fall.
